Graphing Systems of Equations

Parallel Lines never intersect because...

• they have the same slopes. 
• they have the same y-intercept.
• they have different slopes.
• they have different y-intercepts. 

If a system of linear equations has one solution, what does this mean about the two lines? 

• Parallel lines
• the same line 
• Intersecting lines

What is the solution to this system?

• (1, -1)
• (-1, 1)
• (0, -2)
• (2, 0)

Buzz graphed two lines in order to find the solution to a given system of equations.
What is the solution?

• (-1, 4)
• (1, -4)
• (-4, 1)
• (4, -1)

Lesly graphed two lines in order to find the solution to a given system of equations.
What is the solution?

• (-3,-8)

Convert the standard form equation into slope-intercept form.
4x - 3y = 15

• y = (4/3)x - 5
• y = ⅔x - 5
• x = ¾
• y = 27, 239, 430
